Acrobatics Are Easy!

ALTHOUGH the loop is perhaps the easiest of all the acrobatic maneuvers it has always been considered by the general public as being thrilling and spectacular. Perhaps the word “easiest” should be somewhat qualified, for though little difficulty is presented in making the ship climb into an inverted position and dive out of it, a well-shaped or precision loop such as that illustrated in Fig. 1 calls for considerable skill and feel of the airplane.

North Atlantic Ferry

IT is midnight and I am sitting in my “office” sucking on an oxygen tube and wondering why it takes the wing so long to come back up after each dip. My First Officer is there at my side, also with a tube in his mouth, but he isn’t sucking. He is out cold due to the continued effect of high altitude.

A Method for Solving Shear Lag Problems

DESIGN experience has shown that the actual stresses in all-metal wings are sometimes appreciably higher than the calculation according to the customary beam formulas indicates. The reason for this can be roughly described by saying that the wing spars do not succeed in obtaining the cooperation of the metal skin to the extent the customary theory of bending presupposes.
